There's less than a week to go before "Dancing With The Stars" season 21 debuts, and the coveted Mirror Ball Trophy is going to be up for grabs.

The complete lineup and partner assignments was announced in ABC's "Good Morning America" including Tamar Braxton and Val Chmerkovskiy, Gary Busey and Anna Trebunskaya, Nick Carter and Sharna Burgess, Paula Deen and Louis Van Amstel, Victor Espinoza and Karina Smirnoff, Andy Grammer and Allison Holker, Hayes Grier and Emma Slater, Bindi Irwin and Derek Hough, Chaka Khan and Keo Motsepe, Alexa PenaVega and Mark Ballas, Carlos PenaVega and Witney Carson, Alek Skarlatos and Lindsay Arnold as well as Kim Zolciak and Tony Dovolani.

Long-time viewers tune in for the judging as much as the dancing, but the judging table will be short of one familiar face after Len Goodman decided to exit the show after its 20th season. Instead, a guest judge will be featured each week to help Bruno Tonioli, Carrie Ann Inaba and Julianne Hough critique the performances, according to a report from Hollywood Life.

Even before the premiere of the season, several frontrunners are already being leaked to the public. A source from Hollywood Life said that "Nick Carter is going to go very far in the show," the source revealed. "He is a great dancer and many people from the show think he should be a front runner."

However, his professional partner Sharna Burgess was quick to diffuse too much hype on their chances.

Burgess said in an interview with Niagara Frontier Publications that Carter has talent in dancing, but he must shake off his "hip-hop vibe" so he can learn ballroom dancing.

She added, "I would love to say that we're going to win, but who knows at this point? We haven't seen anybody dance; and it seems like a really strong cast."

Another young competitor who is poised to win the audience over is Bindi Irwin, the late Steve Irwin's daughter and the star of Netflix's "Bindi's Bootcamp." The 17-year-old is partnered with fan favorite Derek Hough, which is a major advantage for both charmers.

"She's catching on quick," Hough told ET Online. "It's like she's had this dancer [lying] dormant inside of her body and now we're revealing it. It's awesome!"

Meanwhile, married couple Carlos and Alexa PenaVega could also prove to be formidable on the dance floor, if video clips are a good indicator. Carlos' professional partner Witney Carson posted on Instagram a video of the actor showing off his dance moves and looking comfortable grooving.

"Dancing With The Stars" season 21 will debut on Sept. 14 on ABC.
